I used confluence 4.3.7, and integrated with crowd 2.4.2 following the instruction. The issue is that a user is assigned to group confluence-users in crowd, but the group is not shown up in confluence .

Here are what I did: Checking in confluence <confluence admin> --> users --> detail, shows in groups: no confluence-users,
while in crowd, select users (give username), click group detail, the group confluence-users is there.

I used the manual synchronise, but no change.
